I landed an exclusive interview with Bryce Tierney, a close friend of Jared Lee Loughner, the alleged gunman in the massacre in Tucson Saturday that killed six people, wounded 14, and left Rep. Gabrielle Giffords, the reported target, fighting for her life. In the interview, Tierney talks about his relationship with Loughner, why he thinks his friend might have targeted Giffords, and what Loughner said in a previously unreported 2:00 a.m. voicemail he left for Tierney.
